Application filed August; 26, 1887. Serial No 247,972. (No model.)

To all 1071 0721, it may cancer/1 .Be it known that l, l I'ENRY ll.llYLAND, a citizen of the United States, residing at Pittsburg, in thecounty of Allegheny and State of 5 Pennsylvania, have invented certainnew and. usefu1 Improvements in lnj eetors for Burning Petroleum inFurnaees; and l elare the following to be a full, clear, and exaetdescription of? the invention, sneh as will enable others skilled in.the art to which it appertains to make and use the same.

My invention relates to 1.:eehanism and apparatus t'or vaporizing andspraying hydrocarbon oils to be used as fuel in metallurgiealoperath'ms, and partienlarly for use in a furnaee for welding pipe.

The nature of the invention consists of eonstruetions and eombinations,all as hereinatter deseribed in the speeilieation and pointed out in.the claims, ret'erenee being had to the aeeoin mirving drawings, inwhichhignre l represmlts a side elevation of a t'urnaoe, a seelion ol'the oil-lwater, and an 2, a transverse (.5l(\'tl'.lt)ll ol? theoil-tank; Fig. seetion ol the t'urnaeeon line 2 ing one manner of ap'ilying iny deviee; Fig. .l, a side elevation of the injeetor; frontview of the injector with the easting that forms the mixing-ehamberremoved; Fig. 5, a longitudinal seetion. of the injeetor; Fig.

A represents a furnace, whieh may be ol any desired form; ll, anoil-heat er; t, a tank, and D an injeetor.

The furnace represented is the kind ordinarilyused for welding pipe. ltis,however, provided with additional features, \vhieh will now bedeseribed.

A isa perloral ed bridge or areh of any desired form and hieati-ul inthe fire-box. It is shown supported by the gratebars; but the 2, Fig. 1,showdo hereby deinto sev- I lat ter may be removed and the archsupported in any other manner.

In the front wall of the turnaee are opening's A" for the injeettn' l),and in the ashpit lbetween. the tire-box is a blast pipe, 1 lo supilying air. I i A" is a steam-pipe leadlng lrom a suitable geneiator andhaving a braneh, A", leading into the 'l'urnaee. 'lhis braneh ismnneeted l with a series of pipes-A, loeated between the 5 bridge andthe front wall. ol the l'uirnaee, and l whieh are preferably arrangiulas shown in dotted lines, .l ig. i. From these pipes a sn- 1 perheated-slea1n pipe, A leads to the injeelor l), and eonneeted to the latterin a manner thatwill hereinafter be deseribed. The pipe A is extended toan oil-heater, l arranged at any suitable point and eonneeted at one endot' a steam-(soil, ll, inelosed by the drum 3' "lheother end ol" theeoil extends outside ,ol' the drum li and is provided with a p teoek,(I, whieh, when open, allows the waIere." l eondensalion to eseape fromthe eoil, and also allows the steam to have a tree (-ireuhition lthrough the eoil it it be desired to raise the l temperature in theheater 1 l The drum B is provided with a thermostat, i 7), asight-glass, In, an oil-exit pipe, l-lv, whieh l l l I leads to theinjeetor l), and an oil-supply pipe, ll", leading to the tank and havinga S strainer, I), 'ilaeed at, any suitable point. This strainereonsistsot' a eoupling somewhat similar in term to a globe-valve,instead, however, of a valve-seat, that part of the deviee is .rabbetedto reeeive a filter, 1)", ol any suitable material, wire-gauzebeing thematerial shown. It is seeured in plaee hy the ring I), \vhieh is serewedonto the vertieal t'aee oi the. rabhet. Above this ring a eln-nnber, ll,is formed and eonm ets with the inhtpipe b The upper part of the chamberis elosed by a sermvwap, I), whieh ean be removed when aeeess to theehamber be desired to elean the :t'aee of or remove the tiller from theeonp ling. 5 All the injeetors are eonneeted to the oll- P pe ll b\'vertioal pipes l3 and to the steamsnperheater pipe A' by verticalpipes A In eaeh injector the pipe 'B"leadst0 an oil-ehamher, (7, formedof a (nip-shaped casting, d, and I having a nozzle, d screwed into thefront end and having a flange, d, overlapping the easting' d Theinterior of the nozzle (Z is bellshapecl to receive a valve, (P, whichis moved.

in and out ot the same by a screw-threaded stem, d extending through ascrmr-threaded gland, 11", secured in place in casting (I by serew 1/and provided with a packing between its end and the lips r! on thecasting d. A series ol' openings, (7, radiate through the walls of thenozzle and are (.OYtl'Ctl by nipples d, screwed into an enlargement ofthe holes (1" and project ing at. right angles to the length of saidnozzles and on a. line with nipples screwed into the flange d", whichforms the l'ront end of the annular steamchamln-r il. 'lhis chamber isformed in an am1ulns,l), in \vhieh the casting-d is seated, and isprovided with a steam-sup 'tly port, it", and a screw-t hreaded flange,(1, enci reling the flange d, the nipples in which register with thesteam-ehaml)er d and are held in place by the eonoidal casting I),screwed into the flange (1 ol' the casting l), which has packing, tl",between it and the tlange d. lletween the annulus l)and the eastingdisan annular air-passage, d, leading to a series of 'lliese ports 5 lannular stm'nn-ehainher, a casting having an ports, 17', formed incasting d. d open into an annular chamber, d', l'ormed in the IlUZZlUIIHIHl havingexit-portsd ",leading into the mixing-ehamber l), l'ormedbvtho casting l)'- at a point between the nipples il 1/, so that theblastol' steam passing through nipples 1/ will draw a current of. airintothe miXing-ehamber I). 'lhis mixing-ehamber is divided into the samenumber ol' compartments as there are nipples d in the device by acasting, l), which consists of a nozzle, (1' having partitions 1/ whichextend rearwardly beyond the nozzle to any desired distanee.'lhepassages d l'ormed by these partitions r /'-,are provided with anexit-opening, at the Forward end.

The eastingl is seeured in place b a bolt, (T that is screwed into thehead of nozzle To the trout end of casting is secured a, casting, l), ofthe same shape but. slightly larger than that part ot' the casting l) towhich it is attached to form a steam-chamber, having an exit-opening, d,at its front end and at a-point where it eommingles with the vaporpassing tln-imgh the (awnings r1. '.lhise.hamln .r is supplied withsteam by a pipe, A", leading from the vertical pipe A.

The operatirm of this device is as Follows: Oil and steam arerespectively admitted to chambers 17 and d and the. valve (1 set toallow the desired amount of oil to escape through the nipples d", atthe. lips ol' which it is impacted upon. by the blasts of steam passingthrough the nipples d, which also draws in snllioient air through theair-ports (1 to make the proper mixture in the mixing chamber orpassages formed by the easting I). As it escapes through the openings(1, it is impacted upon bya current of steam passi 11;; through theexit0peni1'1gs in the chamber (7 This mixture of oil, steam, and air ispassed into the furnace and projected against the perforated arch orbridge A and burned. To assist in the proper: combustion oi the mixture,a blast of air is supplied thrtnigh pipe A", which air comming'les withthe irivtnre as it breaks up at the arch or bridge and forces it up tothe crown of the furnace and then down upon the hearth in thetape-cliamber. also snperheats the steam passing through the pipes A,which lead to the i.n; 'e i'tor.

The oil isheal ed to the proper temperature by the steam-pipe in thedrum bet'ore it is fed to the injector, and by taking theoil from thelower part of the drum there is no danger of residual oil remaining inthedrum to clogup the machine.

l do not herein claim the particular eonstrnction olfurnace shown inthis application, as that matter forms the subject of a separateapplieation, No. among, tiled March In, isss.

What l claim as new is----- l. The combination of a casting having anoilehamber part1 inelosed byandhavingan air-space between it and saidsteam-chamher, a nozzle havingnipples, amt a 'l'lange provided win. nip,les arranged at right angles to the nipples on the nozzle, and saidnipples having eommnniealion with said oil and steam chambers, and anozzle or casting, D covering said nozzle and flange and having aeontraeted exit-opening.

L. 'lhe combination ol' a casting lntving an annular steam-ehamher, aeasiing having an oil-elnnnber partly inclosed. b said steamehaml'ier, anozzle having nipples, and a flange provided with nipples arranget'l atright angles to the nipples on the nozzle, and said nipplescommunieating with said oil and steam chambers, and a nozzle or casting,D etitvering said nozzle and llange and having a contract ed ex 1t-openi n :3. The combination of a casting having an annularsteam-chamber n-ovided with nipples, a casting having an oil-chamber, anoz zle having nipples arranged at right angles to the nipples on thesteanrchamber and comn'nmieating with the oil-chamber, a castingcovering said nipples, and a casting secured to the nozzle and havingtwo or more parti tions, which form mixing-ehambers for each set ofsteam and oil nipples.
